Isobar - 1manband gave you a perfect example - PCFG. Completely permitted operation, and lots of wonderful new infrastructure, and a total scam.
I have seen it many times myself - mining scams will spend a lot of money to create the image of a legitimate operation. They will build offices, process areas, maintenance buildings, "proprietary extraction equipment", and hire consultants to do some basic permitting. Creating a "story" is important, and some money spent upfront will buy a lot of loyal investors who will defend the company down to their last dollar. Then, when there is still no gold, and the share price has dropped 99%, they will finally realize they've been had.
Depending on how much money you have invested, I'd recommend contracting with a registered mining engineer or geologist to look over the data, and maybe do another site tour. I'd show up unannounced, if possible, and it may have a different appearance than on the day you were there before (LOL).
Take it from folks on this board who have been in the mining business a long time, URHG is no different than any of the other hundreds of desert dirt scams. 1manband walked you through the interwoven connections between URHG and other documented scammers. Good luck.
